context_page_description: Berghia stephanieae is a species of sea slug, an aeolid nudibranch. It is a marine gastropod mollusc in the family Aeolidiidae. It was previously known as Aeolidiella stephanieae.
context_section_description: Juvenile stage (40-60% of development): At this stage the rudiments of oral tentacles (2nd pair of cephalic tentacles) and the paired, dorsal cerata appear.
  The size of the body increases one third in contrast to the previous developmental stage. As the development continues, the length and the thickness of the rhinophores and oral tentacles increases as well as the body size. At this stage additional pairs of cerata appear and on their tip the filled cnidosacs can be detected for the first time.
caption: Drawing of dorsal view of juvenile (40% of development):                  - (light green) longitudinal muscle fibers,   - (black) circular muscle fibers,   - (white) oblique muscle fibres,   - (brown) anlage of the buccal musculature,   - (apricot color) mouth,  ot = the anlage of oral tentacles,
   r = rhinophores,
   c = the first cerata pairs,
   e = eye.
   The total size is about 600 μm.
